Comparison of physiological and post-endovascular aneurysm repair infrarenal blood flow
(2017)Endovascular aneurysm repair (EVAR) of abdominal aortic aneurysms results in redirection of blood through the deployed endograft (EG). Even though EVAR is clinically effective, the absolute flow restoration is not warranted. ... -
Effects of anti-inflammatory treatment and surgical intervention on endothelial glycocalyx, peripheral and coronary microcirculatory function and myocardial deformation in inflammatory bowel disease patients: A two-arms two-stage clinical trial
(2021)Sixty inflammatory bowel disease (IBD) patients (45 Crohn disease and 15 ulcerative colitis, 40 ± 13 years, 53% male) were examined at baseline and 4 months after intervention (surgical (35 patients) or anti-TNFa treatment ... -
Endograft Specific Haemodynamics After Endovascular Aneurysm Repair: Flow Characteristics of Four Stent Graft Systems
(2019)Objectives: The implication of haemodynamics in the occurrence of complications after endovascular aneurysm repair (EVAR) has been raised in the literature. Different aortic stent graft configurations may lead to different ... -
Haemodynamic performance of AFX and Nellix endografts: A computational fluid dynamics study
(2018)OBJECTIVES The objective of this study is to analyse the flow conditions in the AFX and Nellix endografts (EGs) accounting for their postimplantation configuration in patients with an endovascular aneurysm repair-treated ... -
Hemodynamic profile of two aortic endografts accounting for their postimplantation position
(2017)Endovascular aneurysm repair (EVAR) is a clinically effective technique for treating anatomically eligible abdominal aortic aneurysms (AAAs), involving the deployment of an endograft (EG) that is designed to prevent blood ... -
Imaging of impingement syndromes around the hip joint
(2017)Impingement syndromes are increasingly recognised as significant causes of hip pain and dysfunction. A broad spectrum of intraarticular and extraarticular conditions has been implicated in their pathophysiology. Physical ... -
Imaging of traumatic lesions of abdominal viscera
(2002)Trauma to the abdomen accounts for approximately 10% of trauma deaths. The injury may be blunt or penetrating. Abdominal organs are frequently injured from blunt trauma. Rapid acceleration-deceleration of abdominal viscera ... -
In-stent graft helical flow intensity reduces the risk of migration after endovascular aortic repair
(2019)During the last years endovascular aneurysm repair (EVAR) became the elective treatment for abdominal aortic aneurysms (AAAs) thanks to lower mortality and morbidity rates than open surgery. In face of these advantages, ... -
Oscillatory pressure-driven rarefied binary gas mixture flow between parallel plates
(2021)The rarefied, oscillatory, pressure-driven binary gas mixture flow between parallel plates is computationally investigated in terms of the mixture molar fraction and molecular mass ratio of the species, in a wide range of ... -
Remodeling effects of carotid artery stenting versus endarterectomy with patch angioplasty in terms of morphology and hemodynamics
(2022)Background: Carotid endarterectomy (CEA) remains the first-line treatment option of symptomatic and asymptomatic carotid stenosis, while stenting (CAS) is reserved for selected patients at high surgical risk. Here, we ... -
Suture Line Response of End-to-Side Anastomosis: A Stress Concentration Methodology
(2015)End-to-side vascular anastomosis has a considerable complexity regarding the suturing of the juncture line between the artery and the graft. The present study proposes a stress–concentration methodology for the prediction ... -
Xanthine oxidase inhibitors may prevent or slow chronic kidney disease even in the absence of hyperuricemia
